Today Canyon released the new Sender CFR downhill bike which is said to be lighter and faster than the previous iteration.
Perhaps the bigger win for riders is the prioritizing of rider fit plus the ability to customize the geometry to suit any gravity run or riding style. These features make this new Sender one of the most versatile off-the-shelf, or should that be, out-the-box, gravity bikes on the market.
The new Sender features adjustable reach and chain-stay lengths which enables riders to tune their bike to suit their riding style or the track being raced. The Large and Extra-Large sizes get the full 29er treatment whilst the Small and Medium models run on a mullet setup. Other changes include carbon chain and seat stays, a new shock-mount location and new kinematics which yield less energy-sapping pedal kickback and more progression.
How did you reduce the weight? The weight savings are the result of small changes. If you had to point to the biggest weight savings, it’d be the move from aluminium to carbon chain and seatstays, but the new seat-tube area also delivered significant savings. On the original Sender, the upper shock mount was integrated in the upper seat tube area, which required additional reinforcing material and, therein, weight. We had to employ some very complex lay-up schedules because we essentially split that portion of the seat tube. The new design is simpler, lighter and equally strong. The lower link is now attached to the downtube, closer to the bottom bracket which is an area already reinforced – and this reduces weight too.
Why are you equipping the small and medium Sender with a 29er front and 27.5 rear wheel? A smaller rear wheel is optimal for some riders in certain situations—for example, on steeper courses where shorter riders, in particular, might want more clearance between themselves and the rear tire. With the mullet wheelsize you get the advantage of the big wheel up front—when the trail gets nasty and rooty, you just fly right over the rough stuff—yet you also get the extra clearance out back.
How did Canyon go about reducing pedal kickback? We experimented with several prototypes and with a variety of main pivot locations to find the best balance of suspension traits. It was a lengthy process in which we partnered with SRAM Germany on Project Disconnect—the development of a unique rear hub that helped us precisely measure the pedal kickback forces present in different frame designs. That R&D process helped us reduce pedal kickback to a level that’s no longer detectable on the trail.
A number of bike brands have used idler pulleys to reduce pedal kickback on their DH bikes. Why didn’t Canyon go that route? Idler pulleys can be effective at reducing pedal kickback, but they also introduce weight, drag, noise, and the unnecessary complexity of an additional part. From our perspective, the downsides of an idler pulley outweigh the gains.
MODELS AND AVAILABILITY
The new Sender is available in two models: Sender CFR which is a SRAM & RockShox build and the Sender CFR FMD which is a Shimano & FOX build. Learn more.
